The first constant temperature heater 21 and the second constant temperature heater are both of a conventional structure, and will not be described in detail herein. When heating the water in the bath 7 to be used, water is first added to the bath 7, and the bath cover 2 is covered. The highest water level line of the water in the bath 7 reaching the water bath requirement is a first water level line, the early warning water level line of the water bath heating requirement is a second water level line, the real-time height of the water level line is confirmed by a liquid level sensor, and the values of the first water level line and the second water level line can be input to a controller through a control panel 5. When the added water reaches the first water level line, water is not added into the bath 7 any more, the water is heated by the first constant temperature heater 21, and when the temperature sensor senses that the temperature in the bath 7 reaches the constant temperature value set by the controller, the controller controls the first constant temperature heater 21 to perform constant temperature heating.

Further, install the voice broadcast ware in the box 1, the voice broadcast ware is connected with the controller electricity, after 7 heats of bathroom, reminds the experiment completion through the voice broadcast ware, and the person of facilitating the use in time handles the experiment sample. The experimental samples in different baths 7 have different constant temperature, and the corresponding preheating water tanks 3 in the baths 7 have different temperatures to be heated, so that the heating structures of the preheating water tanks 3 are mutually independent, and the requirements of different experimental samples on different water adding temperatures can be met. In order to reduce the influence of the bath 7 on the test sample, the test sample is not in direct contact with the bottom and sides of the bath 7. Therefore, the clamping table 17 is arranged in the bath 7 in a ring mode, after the experimental sample is fixed on the fixing frame, the fixing frame and the bearing frame are fixed and then are arranged on the clamping table 17, so that the experimental sample is not easy to move or tilt in the bath 7, and the experimental result is not easy to influence.

Further, the bearing frame comprises a bottom plate 16, a plurality of overflow holes 23 are formed in the surface of the bottom plate 16, a plurality of clamping columns 22 are arranged on the lower end face of the bottom plate 16, clamping holes 18 are formed in the clamping table 17, the clamping columns 22 are movably inserted into the clamping holes 18, lifting rods 9 are arranged on the left side and the right side of the upper end face of the bottom plate 16, plate holes are formed in the surface of the bottom plate 16, and the fixing frames are movably clamped on the plate holes. After water is added into the bath 7, the water can overflow from the overflow holes 23 to the bottom plate 16, so that the test sample on the fixing frame can be soaked in the water for water bath heating. Or according to the requirements of different experimental samples, only water vapor is used for constant temperature heating, and the water vapor overflows onto the bottom plate 16 through the overflow holes 23. The bearing frame is movably inserted into the clamping hole 18 of the clamping table 17 through the clamping column 22 on the bottom plate 16, so that the bottom plate 16 is fixed on the clamping table 17, the bottom cannot shake in the water bath heating process, that is to say, the bearing frame cannot shake, the fixing frame installed on the bearing frame cannot shake, and experimental samples placed in the fixing frame cannot shake or topple, so that experimental results are not affected easily. The lifting rod 9 is arranged on the left side and the right side, so that the lifting rod 9 is not easy to influence the fixing frame to be installed on the bearing frame. After the experiment is finished, the trough cover 2 is opened, the bearing frame in the bath 7 and the fixing frame on the bearing frame are taken out together through the lifting rod 9, all experimental samples in the bath 7 can be taken out together, and the operation is convenient. Further, the height of the lifting rod 9 is lower than the notch of the bath 7, and a notch 8 for conveniently grasping the lifting rod 9 is arranged at the edge of the notch of the bath 7. The height of the lifting rod 9 does not influence the cover of the trough cover 2 to be covered on the notch of the bath 7, so that the internal moisture is not easy to be lost. The notch 8 is arranged at the notch of the bath 7, so that the notch 8 exposes the lifting rod 9, a user can grasp the upper end of the lifting rod 9 conveniently, and the lifting rod 9 is used for taking the bearing frame out of the bath 7. Further, a heat insulation sleeve is arranged on the upper end face of the lifting rod 9. Because the lifting rod 9 is positioned in the bath 7, when the water bath constant temperature heating is carried out, the temperature of the lifting rod 9 is also very high, and if an experimental sample is taken out at a high temperature, the lifting rod 9 is likely to scald hands, therefore, the heat insulation sleeve is arranged, the heated temperature of the heat insulation sleeve is small, the lifting rod 9 is conveniently lifted through the heat insulation sleeve, and the experimental sample on the bearing frame is taken out.

Further, the fixing frame includes a base 14, a plurality of connecting columns 24 are vertically installed on the lower end surface of the base 14, an elastic clamping block 25 is installed at the end of each connecting column 24, the elastic direction of the clamping block 25 is vertical to the axis of the connecting column 24, and the clamping block 25 is movably clamped in the plate hole.

When the carrier is lifted by the lifting rod 9, the fixing frame can be lifted stably, so that the experimental sample placed on the fixing frame is taken out stably and is not easy to fall down. The experimental sample on the fixing frame and the bearing frame are taken out or put in together, so that the use is more convenient. Because experimental samples are of many kinds, some experimental samples are placed using test tubes 15; after some slides are used, the slides are placed in the slide cassette 26, and then the slide cassette 26 is placed in the bath 7 for water bath heating. Therefore, the fixing frames are provided with different kinds.

The structure of one of them is as follows, the lower terminal surface of base 14 is equipped with spliced pole 24, the tip of spliced pole 24 is equipped with elastic fixture block 25, the elasticity direction perpendicular spliced pole 24 of fixture block 25, fixture block 25 activity joint is in overflow hole 23, the draw-in groove 27 that is used for placing slide case 26 has been seted up to the up end of base 14. The number and position of the holders can be determined by the number of cassettes 26 to be placed by the user so that the holders can be well secured to the carrier. After taking out the experimental sample or when changing the mount, can pull down the mount from bearing the frame, need pinch the fixture block 25 with fingers for fixture block 25 diminishes, and fixture block 25 breaks away from in the diaphragm orifice, makes mount and bearing the frame and separate.

Since the water temperature around the first constant temperature heater 21 rises relatively quickly and the water temperature in other places rises relatively slowly when the first constant temperature heater 21 is used for heating, the water bath heating is performed with different water temperature differences at the beginning, and the result of the experiment may be affected.

The first stirring blade 19 on the first rotating shaft 20 is driven by the first motor to stir, so that the temperature difference of water in the bath 7 is small, and the influence on the experimental result is reduced.

Similarly, when the water in the preheating water tank 3 is heated by the experimental second constant-temperature heater, the temperature difference of the water in the preheating water tank 3 is larger, the temperature sensed by the second temperature sensor is inaccurate, the water with unstable temperature is added into the bath 7, and the constant temperature of the water in the bath 7 is easily influenced, so that the result of an experimental sample is influenced. Further, a second stirring structure is installed in each preheating water tank 3, the second stirring structure comprises a second motor and second stirring blades 13, the second motor is installed in the box body 1, a second rotating shaft 12 of the second motor, and the second stirring blades 13 are arranged on the second rotating shaft 12 in a surrounding mode.
